When the dial 2 is rotated while pressing the photographing mode setting button 4 when the exposure control mode is the program mode, a photographing mode stored in advance, which will be described later, can be selected. This pre-stored shooting mode is
This is called the shooting software mode (Ps).
In this mode, the exposure for taking a picture with a special image effect is programmed in advance. The shooting software mode includes a portray mode that blurs the background and raises the effect of the person, a red-eye reduction mode that prevents the person's eyes from flashing red, Pan-Focus mode where you can get a picture with focus
A landscape shooting mode in which a sharp photograph with a large depth of field can be obtained, a silhouette mode in which a subject can be emphasized as a silhouette, a sport mode in which an effect of stopping a momentary movement can be obtained, and a subject can be closed. There is a close-up mode for obtaining a sharp photograph with a relatively large depth of field while being zoomed in.

The external display unit 6 displays the shutter speed and the aperture value on the display unit a as shown in FIG. 2, and the exposure control mode, ie, P, S, A, M, and the photographing soft mode are displayed on the display unit b. -Ps is displayed. On the display section c, the photographing software mode is displayed by a pictorial display.

Lv value at 0). When the picture display 21 is turned on by the selection of the portlet mode, the exposure is controlled according to the program diagram 31. At Ev = -1 to 7, shutter time T = 2 to 1/15 and aperture value F = 2.8.At Ev = 7 to 19, shutter time T = 1/15, aperture value F. =
From 2.8, the shutter speed and the aperture value are controlled on a line connecting the shutter speed T = 1/1000 and the aperture value F = 32. As a result, in the portray mode, there is an effect that the background is blurred and the person is raised.

When the picture display 23 is turned on by the selection of the landscape photographing mode, the exposure is controlled according to the program diagram 32. For Ev = 5 to 18, shutter time T = 15 to 1/500
The aperture value is controlled to F = 22, and when Ev = 18 or more, the shutter speed and the aperture value are controlled to coincide with the program diagram 31. As a result, in the landscape photography mode, a sharp photograph with a large depth of field can be obtained.

When the picture display 25 is turned on by the selection of the sport mode, the exposure is controlled in accordance with the program chart 33. For Ev = -1 to 13, shutter time T = 15 to 1/100
0, the aperture value is controlled to be F = 2.8, and when Ev = 13 to 19, the exposure is controlled to be in the range of T = 1/1000 at the shutter time T = 1/1000 and the aperture value F = 2.8 to 22. As a result, in the sport mode, a stop motion effect for stopping a momentary movement is obtained.

When the picture display 26 is turned on by the selection of the close-up mode, the exposure is controlled in accordance with the program diagram 34. At Ev = 4 to 16, the shutter time T is controlled to be 15 to 1/250, and when the aperture value is F = 16 and Ev = 16 to 19, the exposure is controlled to coincide with the program diagram 31. Thus, in the close-up mode, a sharp photograph having a relatively deep depth of field can be obtained while the subject is closed up.

When the picture displays 21 and 23 are turned on by the selection of the pan focus mode, the exposure is controlled in accordance with the program diagram 35. For Ev = 2 to 12, shutter time
It is controlled so that T = 15 to 1/60, aperture value F = 8, and Ev = 12
In steps 19 to 19, the exposure is controlled to coincide with the program diagram 31. As a result, in the pan-focus mode, a photograph in which not only the subject but also the background is in focus is obtained, which is particularly effective in commemorative photography and the like.

Depending on the selection of the silhouette mode, the picture display 24
When is lit, the exposure value determined according to the program diagram 34 is controlled to a value obtained by negatively correcting the exposure value. As a result, in the silhouette mode, a photograph in which the subject is emphasized as a silhouette against the background of the sunset or the like can be obtained. When the pictorial displays 21 and 22 are turned on by selecting the red-eye reduction mode, the exposure is controlled according to the program diagram 31, and the strobe light is further fired. This reduces red-eye
When shooting a person using a strobe at night, the shooting can be performed while reducing the person's eyes from flashing red.

The selection of the photographing software mode in this embodiment is performed by turning the rotary dial while pressing the photographing mode setting button 4 and releasing the hand from the photographing mode setting button 4 when the desired picture display is turned on. I have. In this embodiment, since there are few types of shooting software modes, the setting can be performed without any problem by the above setting method. In order to solve such a disadvantage, another shooting mode setting button 5 (shown in FIG. 1) may be provided separately from the shooting mode setting button 4. In this case, by turning the rotary dial while pressing the shooting mode setting button 4 and pressing the shooting mode setting button 5 when the desired picture display is turned on, the mode represented by one picture display can be set. If the same operation is subsequently performed, the mode represented by another picture display can be set, and as a result, the mode represented by the two picture displays can be selected. The set mode can be released by, for example, pressing the shooting mode setting button 5 for a certain period of time.

For example, taking the picture display of this embodiment as an example, first, the picture display 21 is selected, and then the picture display 23 is selected.
The exposure control mode of the camera is set to the pan focus mode. According to this method, a desired mode can be easily selected even when there are many types of photographing software modes. In this case, when a combination of contradictory effects, that is, a setting of an unprogrammed mode is performed, a warning is issued by blinking a picture display selected later, thereby preventing a setting error.
For example, sports and close-ups are generally a combination of conflicting effects, and the selection of both is a setting mistake. When the close-up photography is selected and the sport is selected later, the picture display of the sport flashes. Of course, the same applies to the case of three or more combinations, and the erroneously selected erroneous picture display is blinked. For example, if a pictorial display for close-up photography is selected while a pictorial display for portray and landscape photography is selected, this setting is a setting error, so the pictorial display for close-up photography is made to blink.

FIG. 12 is a flowchart showing the operation of the CPU when giving a warning using the display as described above. In this flowchart, an example in which two picture displays are selected is described, but it is needless to say that three or more pictures can be displayed. Figure
Steps having the same numbers as those in FIGS. 9 to 11 have the same functions, and thus description thereof is omitted.

In step S50, when it is detected from the signal from the photographing mode setting device 52 that the first picture display has been set, the process proceeds to step S51, where a signal is output to the LCD driver 55, and the set first picture display is output. Turn on the display. If the setting of the first pictorial display is not detected in step S50,
Proceed to step S3.

In step S52, the photographing mode setting device 52
When it is detected from the signal from that the second picture display has been set, the process proceeds to step S53. In step S53, the comparison device (not shown) determines whether or not the set photographing mode, which means both the first picture display and the second picture display, matches the program diagram programmed in advance. Judgment is made, and if it conforms, the process proceeds to step S55, and if not, the process proceeds to step S54.

In step S55, a signal is output to the LCD driver 55, and the set second picture display is turned on simultaneously with the first picture display. In step S54, a signal is output to the LCD driver 55, and the set second picture display is blinked to warn, and the process proceeds to step S52. In step S56, the exposure is calculated based on the program diagram based on the output signal from the photometric device 53, and the flow advances to step S38.

In this embodiment, seven photographing modes are exemplified. However, the present invention is not limited to the seven photographing modes. By turning on the picture displays 21 and 24, a combination of a person and a silhouette can be displayed. Display a number of modes, such as displaying the combination of flowers and people by lighting 21 and 26, and displaying by lighting the pictorial displays 21, 24, and 26 when shooting people and flowers in silhouette It is possible to When a large number of shooting modes are provided, the method of providing the shooting mode setting button 5 as described above is particularly effective.

In this embodiment, the display according to the present invention is displayed on the display section of the camera body.
For example, it may be used for a display unit such as a data pack.

[0043]

As described above, according to the present invention,
It is possible to provide a setting display device that can easily and easily display many shooting modes by displaying one or a plurality of pictures. As a result, many shooting modes can be displayed without enlarging the display unit of the camera. Since there is no need to increase the number of display units, the cost naturally does not increase.

Further, according to the present invention, it is possible to provide a camera setting device with good operability that allows a desired mode to be quickly selected from among many photographing modes. Thus, even if the number of shooting modes increases, it does not take much trouble for the photographer to select a desired shooting mode from many modes.
